Hi iommu developers, I have a question regarding the recent VIOT submission for supporting paravirtualized IOMMU in guests. The spec defines PCI Range Node Structure (5.2.30.3) that maps to a single PCI segment.
Is it possible for the new table to express that an IOMMU covers all PCI segments? This could help support scenarios where: 1. Devices are dynamically assigned to guests during runtime 2. Devices in the same guests are assigned to different segments. Thanks, Yinghan
